Hi everyone. I have a used
Fender Rumble 40 (likely an older 2000s version), and it has always worked well.
I recently bought an
HX Stomp and read that I should connect it to the amp’s EFFECTS RETURN to bypass the amp’s preamp and use the HX Stomp’s amp simulation.
Problem: when I plug into the RETURN, the sound is very poor—there’s hiss, and sometimes it feels like there’s no proper signal. The same happens with the SEND. However, if I plug into the normal input (of the amp), everything works fine.
When I checked the Rumble manual (image below), it explains SEND and RETURN but includes the note “
EXCEPT ON RUMBLE 40,” which is confusing.
What could be happening? Could the SEND/RETURN jacks be faulty, or is the Rumble 40 designed differently?
